Unreliable SIM card detection #25

Open poidl opened 2 years ago

poidl commented 2 years ago

I'm a beginner and I built AOSP 12 and flashed my xperia 10 III following the instructions in [1]. I flashed v3 of the binaries:

SW_binaries_for_Xperia_Android_12_4.19_v3a_lena.zip

(side note: the binaries are hard to find, since at the time of writing, they are not listed in [2] but I later found them in [3]. Perhaps the docs should be updated?)

After booting, the SIM card detection is unreliable. After multiple boot cycles, the SIM card is eventually detected fine and both telefony and data connection through the SIM works. Then after a reboot it is not detected any more for a couple of reboots, until after some more reboots it randomly works again.

I previously had Sailfish OS on the device...does this make a difference?

Thanks for you help!

Actually, some people reported SIM slot 2 is much more reliable, and works when SIM 1 doesn't. Which is even weirder, and prevents you from using full capabilities of the device.

Hi,

I am not sure what firmware did you have on your device so I advise that you use the flashtool to update the software on the device then flash again AOSP. https://developer.sony.com/develop/open-devices/get-started/flash-tool/

Thanks for the advice! I already flashed Sony's stock Android 11 using their tool, and the SIM card detection works fine. I plan to re-flash AOSP in the coming weeks and report back.
